dc.description.abstractCopper is largely used as an animal growth-promoter in intensive animal production. Different Portuguese piggeries are reservoir of tcrB gene (coding for copper resistance) which is disseminated in different enterococcal species, samples and piggeries. Resistance to erythromycin seems to be more common among enterococci harbouring tcrB. This gene is frequently transferred using tetracycline or erythromycin as selective agents. The selection of antibiotic resistance bacteria in the animal setting might be associated with the use of antibiotics and/or biocides. Suplementos de cobre são largamente utilizados como promotores de crescimento na produção animal intensiva. Diferentes suiniculturas Portuguesas são reservatório do gene tcrB (resistência ao cobre), disseminado em várias espécies de Enterococcus provenientes de amostras animais e ambientais. A resistência à eritromicina parece ser mais comum entre bactérias tcrB+. Este gene é frequentemente transferido usando quer a tetraciclina quer a eritromicina como elementos de pressão selectiva. A selecção de bactérias resistentes aos antibióticos no ambiente de produção animal parece estar relacionada quer com o uso destas moléculas quer com produtos biocidas.por
